Once upon a time there were two shapes: a Circle and a Square. They stumbled across a piece of fruit one day, and inside that fruit there were six seeds. Being fair and equal and perfectly nice to each other, each of them took three seeds back to their home.
All three of the Circle’s seeds sprouted and made wonderful trees, but the Square only got two trees. “Ah, that’s just the luck of the draw,” said the Circle. The Square agreed.
